Description

The factory 7.3L Powerstroke Up-Pipes are prone to failure at the factory bellows-style flex joints causing power robbing pre-turbo exhaust leaks over time. But, deleting them altogether in favor of straight tubing can cause serious long term damage from heat expansion and vibration that can cause stress fractures and more exhaust leaks.

With the Sinister Diesel Up-Pipes for the 7.3L Ford Powerstroke, we have instead opted to use much stronger and longer lasting “double slip” joint. The new design still allows the upper and lower sections of the Up-Pipes to move due to heat expansion while maintaining a complete seal. The double slip joints even allow for some flexibility to accompdate aftermarket turbo kits.

Sinister Diesel 7.3L Powerstroke Up-Pipes are made from stainless steel tubing, solid stainless steel CNC flanges, and include the factory cast merge piece. All seams are TIG welded on a fixture for precise fitment tolerances and then back-purged for the highest quality and strongest welds possible. This Up-Pipe kit is designed to fit the 1999.5-2003 7.3L Powerstroke Super Duty and is available in Raw Stainless, Ceramic Coated, or Wrapped finishes for extra protection, durability, and a clean and stylish appearance.

Features:
  • Stainless Steel Construction
  • Mandrel Bent Tubing
  • CNC Machined Flanges
  • OEM Cast Merge Piece
  • Fully TIG welded and back-purged
  • Raw stainless steel finish


  • Kit Includes:
    • Both driver and passenger up-pipes with factory cast merge piece.
    • Hardware and OEM factory gaskets to bolt the up-pipes to the cast merge piece.
    Special Notes:
    ***We recommend purchasing the optional turbo O-ring seal kit with this product to ensure a leak free installation.***

    Guarantee:
    We guarantee that the seams and double slip flex joints will not leak. We have spent countless hours testing, fitting and fabricating these slip joints so that they can/will expand and contract with the heat, but with this design, as they heat up, they only seal better. Without the paper-thin bellows, there is simply no place for the steel to fatigue and crack.
